    Try these steps in order:

    1. Update Office first
      • Open any Office app.
      • Go to File > Account.
      • Under Product Information, select Update Options > Update Now.
      • If Update Now is not shown, select Enable Updates first.
    2. Repair the Office installation
      • Go to Settings > Apps > Installed apps.
      • Find Microsoft 365, Office, or OneNote.
      • Select Modify.
      • Run Quick Repair first.
      • If OneNote still fails, run Online Repair.
      • Online Repair reinstalls Office, so it may take longer, but the referenced guidance says it should not affect documents.
    3. Check whether an add-in is causing the crash
      • Start OneNote in Safe Mode:
        • Press Windows + R.
        • Run: onenote.exe /safe
      • If OneNote opens in Safe Mode, disable add-ins:
        • In OneNote, go to File > Options > Add-ins.
        • Manage COM Add-ins and disable enabled add-ins.
    4. If Class Notebook Add-in is installed, verify it is loading correctly
      • In OneNote desktop, go to File > Options > Add-ins.
      • If Class Notebook appears as an inactive add-in, select Go and enable it.
      • If it shows “Not loaded. A runtime error occurred during the loading of the COM add-in”, use the install/uninstall repair tool mentioned in the support article.
    5. If OneNote is still missing or damaged, reinstall the desktop app
      • Use the OneNote download provided in the support article.
      • The installer matches the existing 32-bit or 64-bit Office installation automatically.
    6. Also install Windows updates
      • Open Windows Update and install available updates.
      • If the issue continues after that, check for updated device drivers, especially display-related drivers.

    If the problem started after opening OneNote and it immediately shows the repair prompt, the most direct path is: Update Office → Quick Repair → Online Repair → Safe Mode/add-ins check → reinstall OneNote if needed.

    Hi Vinod Kumar

    You can refer to AI's recommendations first and follow the suggested troubleshooting steps, especially the Office repair options.

    In addition, since you're using an Education account, I would recommend checking whether OneNote works in the web version (https://www.onenote.com) with the same account. If OneNote Online opens your notebooks successfully, this would indicate that the account and notebook data are intact and that the issue is likely limited to the desktop application on the device.

    Also, please let me know if the error appears:

    • Before you sign in
    • Immediately after signing in
    • Only when opening a specific notebook

    This information can help determine whether the issue is related to the application itself, the Windows user profile, or a particular notebook.

    If OneNote Online is also unavailable, or if you're unsure whether your account has a valid license assigned, I recommend contacting your school's or organization's Microsoft 365 administrator, as they can verify your account status, license assignment, and any service-related issues.

    I look forward to your response..
